That is horrible! I can't believe the person didn't even stop. We have a major problem with people speeding around here too. The bad part is, it's an ongoing problem that people are aware of, yet they let their animals and KIDS!!! play in the road, do whatever. It's crazy! It's not a problem near us because we live in a circle, but on the main streets in the neighborhood...forget it! I always creep because I never know who ar what is going to run out in front of the car!
Here are some steps we've taken that have at least *helped*:
First, call your local police department OFTEN...encourage others to do the same. Eventually, they WILL get tired of you calling and will check up on things.
Secondly, contact your city council and/or attend a meeting. They don't want their name to look bad and want to be elected again...they don't want a bunch of angry citizens on their case because they didn't give attention to areas where it was needed. Keep records of your efforts.
Third, if you still don't get results, call your local news. See if you can get them to do a story...explain the injuries and deaths that have been caused and that your pleas for help have been ignored. They will jump on the chance...especially with you being near a school. It's one thing for the city leaders to look bad to their own citizens...they certainly don't want to look bad to an even larger area.
Lastly, put on oversized sunglasses, take your hairdryer to the street, and act like you are clocking people. Maybe if you present yourself as a lunatic, they will be too worried to speed.
Good luck!
